How to Pass latitude and longitude from one activity to another

I want to pass latitude from one activity to another, but I am a bit confused… I have written the code below.

On button click:

lat = Double.toString(latitude);
// lat = latitude;
Intent intent = new Intent(MapsActivity.this,Restaurant_List.class);
intent.putExtra("lat", lat);
startActivity(intent);

I have declared lat as String. latitude is the variable double which already has the value. So I am passing String…

And on next page:

Intent intent = getIntent();
lat = intent.getDoubleExtra("lat", 19.666);

Of course I have added 19.66, that's why it will show that only. Otherwise if I don't put digits it shows error…

Or if I use getStringExtra(), it shows the by default page whose lat doesn't match with the lat I am passing. I searched a lot on the Internet but didn't get answer.

its Very Simple to Send and Get The intent.

String lat = "10.12456521";
Intent intent=new Intent(MapsActivity.this,Restaurant_List.class);
intent.putExtra("lat",lat);
startActivity(intent);

and In your Next Activity.

String lat;
Intent intent = getIntent();
lat =intent.getStringExtra("lat");

and After you casting into double. Thanks

    String message = String.format("New Location \n Longitude: %1$s \n Latitude:%2$s",location.getLongitude(), location.getLatitude());
    Intent intent=new Intent(MapsActivity.this,Restaurant_List.class);
    intent.putExtra("lat",message);
    startActivity(intent);
Hope this could help you.

lat is a String value obtained after converting latitude which is the actual double value. So, pass latitude through the intent instead of lat.

intent.putExtra("lat",latitude);

Edit: Since the above method is not working for you, try putting your double inside of a bundle.

Intent intent = new Intent(MapsActivity.this,Restaurant_list.class);
Bundle b = new Bundle();
b.putDouble("lat", latitude);
intent.putExtras(b);
startActivity(intent);

Then inside your other activity, do this

Bundle b = getIntent().getExtras();
double lat= b.getDouble("lat");

Change it to String and pass

String latt=String.valueOf(lat);
Intent intent=new Intent(MapsActivity.this,Restaurant_List.class);
intent.putExtra("lat",latt);
startActivity(intent);

And in Restaurant_List class, retrieve the String and convert:

Double lat=Double.parseDouble(getIntent().getStringExtra("lat");

Since the LatLng Object is Parcelable, you can pass it in a Bundle.

Add import in both Activities:

import com.google.android.gms.maps.model.LatLng;

First Activity:

Intent intent=new Intent(MapsActivity.this,Restaurant_List.class);
Bundle b = new Bundle();
b.putParcelable("location", new LatLng(latitude, longitude);
intent.putExtras(b);
startActivity(intent);

Second Activity:

Intent intent=getIntent();
LatLng latLng = intent.getParcelableExtra("location");
double lat = latLng.latitude;
double lon = latLng.longitude;
